The grammar and vocabulary tend to require more syllables and letters (it uses a similar alphabet to English). So a book's printing might require 50% - 75% more pages.

But its not a universally longer language. As an example, prepositions are typically optional ('sa' being the generic preposition). So, texting from dual speakers (most Filipinos in the Philippines speak a local language, Filipino, and quite often English) mixes all three to become exceptionally compact. This intermixing from multiple domains for complete, almost fractal, symbology translates to a lot of domains. I've used code switching for system architecture and mathematical proofs approaches several times over the decades.
